BEST BETS Saturday 9/2:

ANAHEIM

8pm

Pop Music

One of the most powerful cuts on Eminem’s controversial new album “The Marshall Mathers LP” is “Stan,” a quasi-dialogue between a fan and the rap star the fan thinks is dissing him and his little brother. Possibly to prove he’s not that kind of performer, Eminem is taking part in the Power 106-sponsored benefit hip-hop concert Saturday in Anaheim, along with other key rappers including Cypress Hill, Busta Rhymes, De La Soul, DJ Quick and Jay-Z. Proceeds benefit the Knowledge is Power Foundation.

* Power 106 Back to School Powerhouse, Arrowhead Pond, 2695 E. Katella Ave., Anaheim. 8 p.m. $35 to $65. (714) 704-2500.
